My computer speakers are picking up and amplifying a specific FM radio signal. I have noticed that it gets somewhat louder when other things get plugged in to the same surge protector. Does anyone know how to fix this?

Hey guys, thanks for the info so far. I just want to confirm that I am in fact picking up an FM signal. I verified this using a clock radio I have in my room. Can I still use ferrite beads or would something else be better? Thanks.

Along with using shielded cable, make sure that your speaker connections are clean. 91% isopropyl alcohol on a small cotton swab used on the jack and plug may help.

Make sure your power connections are clean.

Try swapping out your surge protector with a new one. If it's been in use for awhile, it's likely that it either has corroded sockets and/or it's been subjected to the effects of a lightning strike. If a lightning strike was nearby, the MOV(s) inside the protector could be fried and you wouldn't know it.

I've also had problems with that in the past. My house is a few hundred feet from a radio tower. Everything in our house used to be able to pick up FM 101.9 (our local station). They moved to another town though, so no more problems.
